I was wondering what you think about keeping larger fish such as Nimbochromis Livingstonii 7" W/F, Nimbochromis Venustus 7" W/F, Dimidochromis Strigatus 7", Red Empress 8", Red Empress 7" W/F, Red Empress 5", Iceberg Ahli 7" W/4F ,Champsochromis C. 4", Yellow Lab. 4" W/2F,( 2 Taiwan reef juvi, 1 Ahli juvi, 2 Yellow lab. juvi's, Blue zebra 3",Nimbochromis Fusc. 3". The tank is 130g, 6' long 2' deep 18" wide. With some large boulders sand substrate and open area for swimming.The tank is doing fine but with alot of light pecking,No major battles as of yet. They do alot of good dancing though. Most of these fish have been raised together so they are used to each other. Can I get your opinion and thoughts of keeping these fish together. (W/F with female) Thanks, C.Calderwood.
